Decision time ( Acts 16 v 31 )

My friend and I were talking about evangelism,he recounted how years ago he got tired of preachers making appeals for people to trust Christ.Then he told he had a dream, it was the only one like it, he ever had,in the dream hr was walking along the sea shore,when he noticed an angel walking beside him.He spoke to the angel as to why he was there, the angel said I want you to catch fish.As they came to certain fishermen casting in their nets. The angel told him to pick up a net and cast it into the sea ,this he did, and did it perfectly,he turned to the angel thinking he would be congratulated,instead the angel said, 'yes you did it well, but why did you not pull in your catch',and with that he awoke.It is not wrong to challenge people to come forth and trust Christ as Saviour, otherwise they may not come.
